its awful to go threw,i had similar with my scan,the doc thought i was 7 weeks pregnant but i wasnt so there was no heartbeat at 5 weeks and they saidthat maybe it was too early so suggested waiting until i was 8 weeks(nearly killed me waiting!) and all was fine,the cramping altho scary is normal i had it terrible too,i know its really hard to not worry its only natural,all the best for Friday!
